The ignition lock cylinder could very well be the problem causing your car not to start. The keyless entry and the radio lock problems are probably not released to the security fault. You should be able to have the radio unlocked and the theft code in the radio reset by your local GM dealer. The fault with the keyless entry system. could be with the remote itself, but proper diagnoses of the keyless entry system should be performed to confirm that.
